DETAILED DESCRIPTION

Overview

Fulfillment centers may be used to fulfill online purchases and other orders. For example, fulfillment centers may include product inventory that may be pulled when an order for a particular product or multiple products is placed. In some instances, the product(s) may be packed and shipped from the fulfillment center. However, the process of obtaining the product(s), packing the product(s), and shipping the product(s) may be complicated due to the amount of inventory, the number of orders to process, the size of the fulfillment center, and/or other factors. In addition, a portion of the fulfillment center designated for packing or shipping may be different than the portion of the fulfillment center designated for holding product inventory. As a result, transportation of products in an order may be time consuming.

In some instances, orders for products may include multiple items. For example, a user may place an order for two or more products. In such instances, the products that are ordered may not be in the same location of the fulfillment center, or one of the products may take a longer time to obtain or pick than the others. As a result, packing of the order may be delayed until all of the items in the order are ready for packing. To improve the speed of processing orders, in certain instances, robots and other technology may be deployed, such that manual efforts can be redirected to other tasks. For example, robots may be used to assist with locating products in an order during a pick process. However, directed picked products to the appropriate packing station and/or location may form a bottleneck in the operation of the fulfillment center. For example, after products are picked, the products may be placed in a container, such as a tote or other container, and directed to sortation machines to direct the picked products to the appropriate packing location. For example, products in the same order may be directed to the same packing location for consolidation and subsequent packing. However, a tote or other container may include products that are to be sorted to multiple different packing locations, and the sortation process may be slowed by sheer volume of products that are to be processed and/or sorted.

Embodiments of the disclosure include methods and systems for automated item sorting that may improve processing and fulfillment of multi-item orders, or orders that include more than one item. Certain embodiments include item sorting systems with modular sorting machines that can be combined to form larger sorting machines, and that include receiving bins coupled to one or more sides (e.g., opposite sides, etc.) of the sorting machine to increase throughput and speed of consolidating items for multi-item orders. Some embodiments include optimized process flows for processing of orders at fulfillment centers, as well as process flows or methods to increase speed of consolidating products in a multi-item order. As a result, throughput of fulfillment centers may be improved, and/or logistics of fulfillment center operations may be less complicated.

Referring to FIG. 1, an example use case 100 for automated item sorting for multi-item orders and an example process flow in accordance with one or more embodiments of the disclosure. Although discussed in the context of online orders, other embodiments may be directed to any suitable use case where products are picked and sorted, such as instances where users may pick up orders rather than receiving a shipment.

In FIG. 1, a fulfillment center may include a robotic storage platform 110, a routing sorter 120, one or more universal item sorters 130, and one or more packing stations 140. The robotic storage platform 110 may be a portion of the fulfillment center at which products picked from product inventory are placed. Robots may be used to pick products from inventory and to deliver to the robotic storage platform in some instances, while in other instances, manual labor or a combination thereof may be used to pick products. The picking process at the robotic storage platform may include locating a product in an order, obtaining the product, and sending the product to the robotic storage platform 110, such as via a conveyor belt. In the illustrated embodiment, products at the robotic storage platform 110 may be placed in a container, such as a tote. The tote may be assigned to, or otherwise associated with, a particular universal item sorter machine. For example, a certain tote may be associated with a certain universal item sorter, such that products that are designated to be picked and placed in the tote are for orders that are to be consolidated at that particular universal item sorter. The association between the tote and the universal item sorter may be static.

At the routing sorter 120, totes including products that have been picked may be routed to the appropriate or designated universal item sorter. For example, the routing sorter 120 may determine an identifier associated with the tote, and may determine the universal item sorter associated with the tote using the identifier. The routing sorter 120 may route or direct the tote to the appropriate universal item sorter.

The universal item sorters 130 may include one or more universal item sorter machines. In FIG. 1, a first universal item sorter 132, a second universal item sorter 134, a third universal item sorter 136, and so forth may be included. Any number of universal item sorters may be included. Some or all of the universal item sorters may be associated with certain totes. The universal item sorters may be used to consolidate or otherwise aggregate products for multi-item orders. For example, a first tote may include a first item of a multi-item order, and a second tote may include a second item of the multi-item order. The universal item sorter may therefore identify the orders associated with the respective products in a tote, and may transport the products to a container, such as a bin, associated with the order. When the order is complete with all of the products in the associated bin, the order may be packed. Accordingly, a specific universal item sorter may be designated for fulfillment of a particular multi-item order. As a result, all of the products in the multi-item order may be placed in totes that are associated with that particular universal item sorter. At the universal item sorters 130, totes that are received via the routing sorter 120 may be emptied, and the products in the respective totes may be transported to the appropriate bins for the orders for which the products were picked. Example universal item sorters are discussed with respect to at least FIGS. 3 and 5-8B.

After a multi-item order is complete (e.g., the universal item sorter has delivered all of the products in the order to the appropriate bin, etc.), the order may be packed at the packing station 140. In some embodiments, one or more packing stations may be included. In some instances, a packing station may service more than one universal item sorter, while in other instances, more than one packing station may service one universal item sorter. In the illustration of FIG. 1, a first packing station 142 may be used to pack orders from the first universal item sorter 132, a second packing station 144 may be used to pack orders from the second universal item sorter 134, a third packing station 146 may be used to pack orders from the third universal item sorter 136, and so forth. At the packing stations 140, the orders may be placed into boxes and sealed for subsequent shipment. The packages may then be processed for shipment to the user.

At the fulfillment center, an example process flow 150 illustrated in FIG. 1 may be implemented to improve the efficiency and/or throughput of the fulfillment center. At a first block 160, items may be picked from the robotic storage platform 110 into a tote that is associated with a specific universal item sorter. At a second block 170, the tote may be sent to the routing sorter 120 for routing to the specific universal item sorter. At a third block 180, the items from the tote may be sorted for an order with multiple item by the specific universal item sorter. At a fourth block 190, the items may be packed into a shipment when all of the items in the order are sorted.

FIG. 2 is a hybrid schematic illustration of an example use case for automated item sorting for multi-item orders and an example process flow in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components.

In FIG. 2, an example layout of a fulfillment center 200 is depicted. The fulfillment center 200 may include a robotic field 210 at which product inventory may be stored for picking, one or more routing sorters 220 that may be used to consolidate products for multi-item orders, one or more universal item sorter machines/walls 230 that may be used to pack multi-item orders, one or more single item sections 260 that may be used to pack single item orders, one or more labeling machines 240 that may be used to apply shipping labels to packages, one or more flat sorters 250 and shipping sorters 270 to sort labeled shipments (e.g., by destination, carrier, etc.) for pickup from the fulfillment center 200. In some embodiments, the flat sorters 250 and shipping sorters 270 may be combined into a single section.

The fulfillment center 200 may implement a process flow 280 for processing multi-item orders. At a first block 282, items for different orders may be picked into a tote that is assigned to a specific sorting machine, such as one of the universal item sorter machines 230. The tote may include items from any order that is being consolidated by the specific universal item sorter machine. The universal item sorter machine may sort singular items into multi-item orders. At a second block 284, the tote may be sent to a routing sorter. At a third block 286, the routing sorter may route or divert the tote to the assigned universal item sorter machine. At a fourth block 288, the universal item sorter machine may sort singular items into multi-item orders. At a fifth block 290, the order may be packed after all items in the order are sorted.

The universal item sorter machines 230 may include bins or containers of different sizes (e.g., small, medium, large, etc.) and may be configured, in one example, to handle items that weigh up to twenty or more pounds. In some embodiments, the universal item sorter machines 230 may include multiple chutes, such as about 328 chutes, and may be configured to sort items at a rate of about 2,100 units per hour. In some instances, the universal item sorter machines 230 may have two inductors (e.g., one on each side, etc.), and may be modular. For example, the universal item sorter machines 230 may each include sixteen expansion modules, where expansion modules may be defined as three two-sided columns next to one another for a total length of about 80 feet. The universal item sorter machines 230 may reduce labor and capital costs associated with processing orders.

In some embodiments, the universal item sorter machines 230 may replace other processes, such as manual processes. For example, manual induction of products from a tote to a sorter machine may be a bottleneck that is avoided by the systems and methods described herein. The universal item sorter machines 230 may be a cross-belt shuttle sorter that sorts singulated products into containers or totes. Universal item sorter machines 230 may be capable of sorting at a rate of 2,100 units per hour. Certain universal item sorter machines 230 may be configured to handle items of up to and including twenty pounds, or more in some instances, with dimensions of about 18″×14″×8″, which may cover almost all products at the fulfillment center 200. The universal item sorter machines 230 may operate as a high-speed, high-destination sort solution that intakes items or packages and sorts them into containers using a shuttle that travels vertically and horizontally inside the machine (or outside in some instances).

Individual universal item sorter machines may be item sorting systems, and may include a number of, such as two or more, modular sorting machines coupled in series, or otherwise adjacent to each other and connected. The modular sorting machines may include a first modular sorting machine. The modular sorting machines may be configured to singulate items from a tote comprising a plurality of items into a plurality of bins (e.g. induct individual items from a bin that has multiple items, and place the inducted items into the appropriate bin, where bins are associated with multi-item orders. The tote from which items are inducted may be associated with the individual universal item sorter machine (e.g., the modular sorting machines that form the individual universal item sorter machine, etc.).

Accordingly, in some embodiments, universal item sorters may be arranged in rows and may receive assigned totes from a routing sorter, thereby streamlining fulfillment center operation and reducing labor and space costs. The universal item sorters may process totes for multi-order sortation and consolidation. As a result, there may no longer be a need to singulate and send items to a wall for manual extraction, because each tote may be assigned to a particular universal item sorter machine. Induct stations can be replaced with universal item sorter machines.

In another embodiment, pickers may pick items directly to a segmented belt conveyor at a station that is near a universal item sorter machine. Other nearby pick stations may also pick items directly to conveyance for the same universal item sorter machine. Picked items being transported to a single universal item sorter machine may merge together to be inducted into their unique universal item sorter machine, where multi-item orders may be consolidated and sent to packing.

Embodiments of the disclosure include automated item sorting for multi-item orders. Certain embodiments may improve processing speed and/or throughput of fulfillment centers. Certain embodiments may improve performance of mechanical equipment for sortation and/or consolidation of items for multi-item orders. While described in the context of online orders, aspects of this disclosure are more broadly applicable to other forms of product sortation.

Example embodiments of the disclosure provide a number of technical features or technical effects. For example, in accordance with example embodiments of the disclosure, certain embodiments of the disclosure may improve processing speed, throughput, and/or efficiency of fulfillment centers. The above examples of technical features and/or technical effects of example embodiments of the disclosure are merely illustrative and not exhaustive.

One or more illustrative embodiments of the disclosure have been described above. The above-described embodiments are merely illustrative of the scope of this disclosure and are not intended to be limiting in any way. Accordingly, variations, modifications, and equivalents of the embodiments disclosed herein are also within the scope of this disclosure. The above-described embodiments and additional and/or alternative embodiments of the disclosure will be described in detail hereinafter through reference to the accompanying drawings.

Illustrative Embodiments and Use Cases

FIG. 3 is a schematic illustration of an item sorting system and additional components in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 3 is not to scale, and may not be illustrated to scale with respect to other figures. The universal item sorter illustrated in FIG. 3 may be the same universal item sorter discussed with respect to FIGS. 1-2.

In FIG. 3, an example use case 300 including a set of totes 310 and an item sorting system, or a universal item sorter machine 320, is depicted. The set of totes 310 may include one or more totes that are assigned to, or otherwise associated with, the universal item sorter machine 320. For example, Tote 1, Tote 35, Tote 3645, and so forth may be associated with the universal item sorter machine 320. The totes may have identifiers, such as alphanumeric or other identifiers. The totes may be used to place items that have been picked into the totes. The items that are placed in the totes may be associated with orders that are to be consolidated by the universal item sorter machine 320. For example, Tote 1 may include item 1, item 16, and item 23, Tote 35 may include item 1656, Tote 3645 may include item 989, item 145, and item 34, and so forth. The item sorting system, or the universal item sorter machine 320, may be configured to receive items from a tote that includes one or more, such as multiple items, and the tote may be assigned to the item sorting system or the universal item sorter machine 320.

The totes 310 may be directed to the universal item sorter machine 320 for sorting and consolidation. For example, items in the totes 310 may be inducted into the universal item sorter machine 320 via a conveyor belt.

The universal item sorter machine 320 may include one or more modules, and may be adjusted in size by adding or removing modules as needed. For example, the universal item sorter machine 320 may include a first modular item sorting machine 330 and a second modular item sorting machine 340. The second modular item sorting machine 340 may be coupled to the first modular item sorting machine 330.

The first modular item sorting machine 330 may include a first support disposed on a first side of the first modular item sorting machine 330, and a second support disposed on the first side of the first modular item sorting machine 330. The first support and the second support may form a first chute between the first support and the second support, as discussed with respect to FIGS. 5-8B. The first modular item sorting machine 330 may include a first bin positioned at a first vertical location in the first chute, and a second bin positioned at a second vertical location in the first chute. The first bin and the second bin may have the same height or different heights. In some embodiments, chutes may be disposed about more than one side of the first modular item sorting machine 330.

The second modular item sorting machine 340 may include a third support disposed on the first side of the second modular item sorting machine 340, and a fourth support disposed on the first side of the second modular item sorting machine 340. The third support and the fourth support may form a second chute, as discussed with respect to FIGS. 5-8B. The second modular item sorting machine 340 may include a third bin positioned at a first vertical location in the second chute, and a fourth bin positioned at a second vertical location in the second chute. The third bin and the fourth bin may have the same height or different heights, and may have different heights than the first bin and/or the second bin. The first bin, the second bin, the third bin, and/or the fourth bin can be rearranged in different vertical locations and chutes, and may be configured to receive items of orders comprising multiple items. In some embodiments, chutes may be disposed about more than one side of the second modular item sorting machine 340.

The respective modules of the universal item sorter machine 320 may include one or more bins, or containers that hold items of a multi-item order. For example, as illustrated in side view 360, the second modular item sorting machine 340 may include a first chute 370, or vertical stacking, of bins, and a second chute 380 of bins. The bins in the respective chutes may be of different sizes or dimensions, or may be placed in different vertical locations along the chute. The universal item sorter machine 320 may include a plurality of bins disposed in an array along one or more sides of the first modular item sorting machine 330 and the second modular item sorting machine 340. The respective bins may be configured to be repositioned within different chutes and/or at different vertical locations. In FIG. 3, Bin 1 and Bin 2 may have the same height, while Bin 3 in the same column or chute may have a different height. Any suitable number of bins may be included in a chute and/or array.

Items or products inducted from the totes 310 may be sorted and directed to a bin associated with the order for which the item was picked. The items may be transported by one or more shuttles 350, which may move in one or more directions within the universal item sorter machine 320. In some embodiments, the shuttles 350 may be positioned outside of the universal item sorter machine 320.

For example, Item 1 may be inducted from Tote 1 and placed in Bin 3, along with Item 989 and Item 34 from Tote 3645. Bin 3 may be associated with an order that included those three items, and may therefore be ready for packing. Similarly, Item 16 may be routed to Bin 4, Item 23 may be routed to Bin 5, Item 145 may be routed to Bin 6, and so forth. Any number of bins, totes, and/or modules may be included.

FIG. 4 is a schematic illustration of an example process flow 400 for automated item sorting for multi-item orders in accordance with one or more embodiments of the disclosure. One or more of the blocks illustrated in FIG. 4 may be performed in a different order or across a distributed environment.

At block 410, items may be picked into a tote that is assigned to a sorting machine. The sorting machine may be a universal item sorter machine, such as that described with respect to FIGS. 1-3. Items placed in the tote may be for different orders. The orders may include multiple items.

At determination block 420, a determination may be made as to whether the tote is full. The determination may be made by a computer system that selects products for picking for a certain tote. If it is determined at determination block 420 that the tote is not full, the process flow may return to block 410. If it is determined at determination block 420 that the tote is full, the process flow may proceed to block 430. At block 430, the tote may be sent to a routing station.

At determination block 440, a determination may be made as to whether the tote is a multi-order tote, or a tote that include items from more than one order. The determination may be made by the same or a different computer system. If it is determined at determination block 440 that the tote is not a multi-order tote, the process flow may proceed to block 470 for packing and subsequent shipment. If it is determined at determination block 440 that the tote is a multi-order tote, the process flow may proceed to block 450.

At block 450, the tote may be routed to its assigned sorting machine. At block 460, the items from the tote may be sorted for multi-item orders. The sorting machine may sort the items from the tote into designated bins for multi-item orders. At block 470, the items may be sent to a packing station for packing and subsequent shipment.

FIG. 5 is a schematic illustration of a perspective view and various detail views of an item sorting system 500 in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 5 may not be to scale, and may not be illustrated to scale with respect to other figures.

In FIG. 5, an item sorting system 500 may include an induction portion 510, where items may be inducted from totes that are assigned to the item sorting system 500. The item sorting system 500 may be a universal item sorter. The item sorting system 500 may include a first set of chutes 550 on a first side 520 of the item sorting system 500, and a second set of chutes 540 on a second side 530 of the item sorting system 500. The chutes may be vertical columns formed along the respective sides. One or more of the chutes may include one or more bins positioned at various vertical positions along the chute. The bins may be removable from the chute in some instances, and may not be removable in other instances. The bins may be of different sizes to accommodate different numbers of items and/or items of different sizes.

FIG. 6 is a schematic illustration of an end view and perspective view of an item sorting system in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 6 may not be to scale, and may not be illustrated to scale with respect to other figures. The item sorting system illustrated in FIG. 6 may be the same universal item sorter discussed with respect to FIGS. 1-5.

In FIG. 5, an end view of a universal item sorter 600 and a perspective view of the universal item sorter 600 is depicted. As illustrated in FIG. 6, the universal item sorter 600 may include a first bin 610 and a second bin 620 disposed in a first chute 660 on a first side 650 of the universal item sorter 600, and a third bin 630 and a fourth bin 640 disposed in a second chute on a second side of the universal item sorter 600. The bins may be of the same or different sizes. Any number of chutes and bins may be used. The bins may form an array along the first side 650 and/or other sides of the universal item sorter 600.

The universal item sorter 600 may include a plurality of modular sorting machines coupled in series. The universal item sorter 600 may be configured to singulate items from a tote that has a plurality of items into the plurality of bins.

As illustrated in FIG. 6, as well as in FIGS. 7-8B, the chutes may be formed between supports that are disposed along one or more sides of the universal item sorter 600. The supports may include vertical support members, as well as additional support members that form a triangular support along an upper portion of the universal item sorter 600. For example, the universal item sorter 600 may include a first support coupled to the universal item sorter 600, and a second support coupled to the universal item sorter 600, where the first support and the second support together form the first chute 660 therebetween, and where the first support and the second support are configured to support a plurality of bins (e.g., the first bin 610, the second bin 620, etc.) disposed vertically in the first chute 660. The first bin 610 of the plurality of bins may be disposed in the first chute 660 at a first vertical position, and the second bin 620 of the plurality of bins may be disposed in the first chute at a second vertical position, where the first bin 610 and the second bin 620 are configured to receive items associated with multi-item orders. An order or arrangement of the bins may be rearranged in the first chute 660 and/or in a different chute or vertical position.

FIG. 7 is a schematic illustration of a top view and side view of an item sorting system 700 in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 7 may not be to scale, and may not be illustrated to scale with respect to other figures. The item sorting system illustrated in FIG. 7 may be the same universal item sorter discussed with respect to FIGS. 1-6.

In FIG. 7, as illustrated in top view, a universal item sorter may include a plurality of supports 710 disposed along one or more sides of the universal item sorter. The supports may form chutes between a pair of supports. For example, a first chute 720 may be on a first side of the universal item sorter, and a second chute 730 may be on a second side of the universal item sorter. The respective chutes may be formed between supports. As illustrated in the side view of FIG. 7, supports 740 may form a chute 750 therebetween.

Bins disposed in the chutes may have different dimensions. Bins may be grouped by dimension in some instances. For example, smaller bins may be near a left side of the machine closer to an inductor, while larger bins may be further away. In some instances, bins of various sizes may be interspersed. For example, a first bin 760 may have a first height, and a second bin 770 may have a second height that is different than, such as less than or greater than, the first height. In some instances, bins in the same chute may have different heights. In some embodiments, a gap may be disposed between a bottom of a first bin and a top of a second bin, such that items in the second bin can be removed without removing the first bin from a chute. In some instances, gaps may be about four inches, while in other instances, gaps may be about eight inches.

In some embodiments, the plurality of bins may include bins of different heights, and the plurality of bins may be disposed in an array configuration. For example, an array of bins may be formed in chutes along a side of the universal item sorter.

FIGS. 8A-8B are schematic illustrations of various views of an item sorting system with supports in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustrations of FIGS. 8A-8B may not be to scale, and may not be illustrated to scale with respect to other figures. The item sorting system illustrated in FIGS. 8A-8B may be the same universal item sorter discussed with respect to FIGS. 1-7.

In FIG. 8A, a universal item sorter 800 is depicted in perspective view and in detail view. Shuttles used to transport items may move in one or more directions internally or externally with respect to the universal item sorter 800. For example, shuttles may move laterally along direction 820, and vertically along direction 830.

As illustrated in FIGS. 8A-8B, the universal item sorter 800 may include supports that support bins positioned in chutes between supports. Supports may include optionally angled members 810 coupled to the universal item sorter 800 (e.g., a frame or other component of the universal item sorter 800, etc.), and a vertical support member 840. For example, a first support may include two discrete members 810 that are angled with respect to a frame or other component of the universal item sorter 800. Specifically, the first support may include a first member 810 coupled to the universal item sorter 800 at a first distal end, and a second member 812 coupled to the universal item sorter 800 at a first distal end of the second member 812, and to the first member at a second distal end of the second member 812. The first member 810 and the second member 812 may extend from the universal item sorter 800 at an angle, such as equal and/or opposite angles. For example, the first member 810 and the second member 812 may form a triangular geometry 850. In other instances, the first member 810 and/or the second member 812 may form a ninety degree angle with respect to the universal item sorter 800 (e.g., a frame of the universal item sorter 800, etc.), or any other suitable angle. In some embodiments, the first member 810 and the second member 812 may be coupled to form an integrated member. Some embodiments may include a single member instead of the first member 810 and the second member 812.
